چکیده انگلیسی
Inverse gas chromatography was used to characterize both doped, the undoped polyaniline (PANI), and its blend with nylon-6 using 27 solutes. The change in the morphology of these polymers was detected between 80 and 180 °C and was complemented by the degree of crystallinity. ΔHs1 values of all solutes – pure polymers were found endothermic and exothermic for the blend. The χ′23χ′23 depended on the chemical nature of solutes; a correction measure was not successful in obtaining the true values of χ′23χ′23. χ′23χ′23 showed a phase separation of the blend (60:40 w/w) between 80 and 180 °C. Blending nylon-6 with PANI has lowered the dispersive surface energy of PANI while increasing the surface energy of nylon-6.
